ill??? to that portion of a box machine milazrled to supply and deliverheads to the uiecnanisln for assembling the elements of the heir.

fine object of the invent ion is the provision of an ellicient mechanismfor Supporting a plurality of box blanks in convenient poeitiou anddelivering them successively from such position.

Another object is the provision of a pi'ac tical feeding mechanism todeliver the box blanks or heads in an accurate manner so as to conformwith other mechanism adapted to operate tlicrcon. c

LStill another object is the provision of e'llicicnt guiding andpressing devices to cooperate with the devices to which theheads are fedand insure the exact positioning of the heads on the latter,

The inventionaccordingly consists in thefealiirree of construction,combinations of f and r-irrangcment of parts which :i'n 'liiied in theconstruction hereinafter set forth, and the scope of the apcation ofwhich will be indicated in the in the accompanying drawings, whereinimilar reference characters indicate similar arts: thri'nighout theseveral views, Figure I A I n 1' 1 :1 side elevation of the mechanism.partly in array; Fig. 2 is a rear view thereof;

ing certain associated cooperating mecha-. nismi The in ention formingthe subjectanattcr of this application is disclosed in applicants priorapplication Serial No. 492.029, tiled April El, 1909. In said prioramilicalion a ho): is made by assembling a box head and a box flange inpredetermined position, folding the flange around the head pasting theends of the flange together, and pasting an extension of the flange tothe bottom of the head to secure the head and flange together. The headand flange are nssemhled on a, form carrier comprising; a huh "210having a plurality of radial arms 21] arranged equidistant about thehub, the carrier being secured with its hub to a horizontal shaft, 212journaled transversely in a bearing on the adjacent. parts of the mainframe A and rotated intermittentiy by any suitable mechanism so that itcoincs to rest at i1.- lervals with one of its arms projecting!vertically upward, and the others disposed at other positions forpurposes not here required to explain. The mechanism disclosed toaccomplish the intern'iittcnt rotary movement of the carrier comprises amutilated pinion 213 mounted on a countershaft 206 and provided onone-half of its periphery with gear teeth while the remaining half isplain and concentric, and a mutilated gear wheel F314 secured to theouter end of the rotatable carrier-shaft and provided equidistant on itsperiphery ivith lour toothed segments or sections which are adapted tohe engaged successively by the toothed por tion of the pinion 213 andfour locking faces alternating with the toothed sections and adapted tobe engaged successively by the plain concentric locking face of thepinion, the relative size and construction of this pinion and gear wheelbeing such that the gear wheel is turned one-quarter of a rotation bythe pinion during each complete rotation of the lattcn and the rotatablecarrier is held at rest after each quarter step forward to permit offeeding a box head to ,the carrien and carrying the head to thc flangefor assembly therewith.

At its outer end each carrier arm is pro vided with a form, former;mandrel or block 21?} preferahlv of rectangular shape, npon which thehead is received, the block being preferably constructed to nerve apnewmat-ii. gripper and having cliennels 219 communicating with a passageway220 in the carrier arm, which passageway is at intervals placed incommunication with an exhaust device. The head is fed from the magazineto the face of the former or block,

and the outer edge of a front jaw Z12, ar-

ranged transversely at the front edge of each former and mounted on theouter arm of a rock lever 243 oh the carrier arm, projects outwardlybeyond the face of the former so as to operate as a gage or shoulderwith which the front edge of the head engages while the same is beingpushed from the bottom of the stack upon the former, the operation ofthe machine serving to move the jaw 242 into gaging position when theformer is in receiving position relative to the heads in the magazine.

The blanks or box heads B delivered to the former are preferablyrectangular in shape and composed of paper, pasteboard, etc., as setforth in the pri r application, and are supplied from a stac containedin an upright magazine which is arranged in the upper front part of themachine and which preferably consist of two upright side walls 193adapted to engage with opposite side edges of the heads, a pair ofupright inner flanges or shoulders 194 arranged on the rear ends of theside walls and adapted to engage with the front edges of the box heads,and two upright inner shoulders 195 at the front ends of the side wallswhich are adapted to engage with the rear edges of the box beans, and abottom 196 which extends across the lower end of the magazine andsupports the stack of heads therein. The heads are feed or removedsuccessivel from the bottom of the stack, in a predetermined path, orplane by means of a delivery device which preferably consists of ahorizontally and longi tudinally-reciprocating plunger or followercomposed of two sections 197 which are arranged side by side and guidedin grooves 198 in the upper side of the magazine bottom, each sectionbeing provided with a rearwardly-facing shoulder 199 at its rear end anda cross piece 200 connected with the front ends of the plunger sections.In its retracted position, the plunger is arranged with its shoulders infront of the stack of heads in the magazine and upon moving the samerearward, these shoulders engage with the rear edge of the lowermosthead in the magazine and push the same rearwardly from the bottom of thestack and out through an opening or throat which is formed at the lowerrear end of the magazine and which is of such height that it permitsonly one head at a time to be ejected rearwardly from the magazine.After the plunger or follower has thus removed the lowermost head fromthe stack, it is returned to its foremost position with its shoulders inpermitting the latter to pivoted on the adjacent part of the frame andhaving an upper arm which is connected by a link 2203 with ahorizontally and longitudinally sliding bar 204 connected with thefollower crosspiece, and a rotatable cam 205 engagingwith the lower armof the lever 202. The cam 205 is secured to the shaft 206 which isiournaled in bearings on the adjacent part of the frame and is driventhrough a chain wheel 209 secured thereto, On account of the springmeans for effecting the discharging movement of the follower, the feedof the blanks from the magazine is in a yielding manner, such yieldingfavorably qualifying any tendency to crush or bend the blanks, andsubstantially avoioing fracture of the machine should any obstruction orforeign object he accidentally presented to the mechanism.

As the box heads are discharged successively from the under side of thestack in the magazine, they are carried one at a time rearwardly,downwardly, forwardly and upwardly in a circular path and each assembledwith a flange strip and binder strip, as hereinbefore explained. Each ofthe formers is carried into a position in rear of the head magazine atthe same time that a box headis being discharged from the mags.- zine,whereby this head is delivered on top of the respective former which atthis time has its face arranged uppermost. Immediately after the headhas been thus delivered upon the former from the magazine, the airgrooves of the former and its respective branch passage are connectedwith the air.

exhaust device. causing the box head to be come pneumatically attachedto the gripis effected by V and bring the next following lowerping faceof the former. As the box heads are fed from the lower end of the stackin the magazine, the same are guided and pressed downwardly against theface of the former which at this time is moving into position in rear ofthe outlet of the magazine for receiving the same, thereby insuringreliable attachment of this head to th former by means of the externalair pressure which is produced by connecting the air passages of thisformer with the air exhausting device immediately after the former comesto rest in rear of the magazine outlet. The preferred form of guidingand pressing doe vice for this blank pressing and deflecting roller 236arpurpose consists of a horizontal rang l transvo sel in rear of theoutlet of tbs o line 'nlih its lower part normally inn-:11 ring ilzrpathof tho head which is being discharged from the magazine, two vortirallvlnUYlilllQ rods 23?
